Question from "Jay AT hand-you DOT com DOT tw"
MTD 问题
目前使用 Nor Flash 放置U‐Boot 以及uImage 想请问如何正确的挂载以及存取NOR 剩余空间、Nand Flash
空间
参考网页为
docs.blackfin.uclinux.org/doku.php?id=linux‐kernel:drivers:bf5xx_nand
docs.blackfin.uclinux.org/doku.php?id=linux‐kernel:jffs&s[]=nand
docs.blackfin.uclinux.org/doku.php?id=linux‐kernel:yaffs&s[]=nand
尝试照着步骤使用jaffs 格式 放入Nor Flash 或 Nand Flash 中
但皆无法正常开机 ,（所以目前放入Nor Flash 使用最原始的格式）
nand設定1.pdf
nor設定1.pdf

“但皆无法正常开机”
有无详细的出错信息？还是Uboot 也无法起来？

U-boot 可正常启动 但是如果使用jffs 格式
参考 docs.blackfin.uclinux.org/doku.php?id=linux-kernel:jffs
要从NOR FLASH 读取uImage 時 都會出現 bad image file
另外如附件说明的在uClinux 底下 我NAND FLASH 可以在/proc/mtd里看到 也可mount到/mnt底下 并且会出现 "lost+found"的文件夹
但从开机后我在 "lost+found"里面建立的数据就全部消失了 我该如何做存储的动作呢？？

Could you use jffs2 instead of jffs? jffs was not tested in 08R1.5.

最多只能顯示出"lost+found"
mtd需要事先將FLASH 做 IMG檔嗎？like "jffs2.img" or other.....
需要打什麼指令讓檔案能夠回存至flash中呢？？？

Select JFFS2 option in kernel menuconfig. The Makefile of uClinux-dist will create the rootfs.jffs2 image in folder images for you after building.

I have Select JFFS2 ....
關於存取nand flsah
我的测试流程是..
依照 (附件中..)Nand.doc的设定 menuconfig
在uboot状态下 先将sw1 切换成 ON ON OFF ON 将uImage 下载到 memory中
之后切换回 OFF OFF ON OFF
执行"bootm "进入uClinux
执行" cat /proc/mtd" 确认是否有 mtd讯息....如果有就
执行" mount -t JFFS2 /dev/mtdblock0 /mnt/ "
到mnt/目录下 只看到 "lost +found"
在"lost +found" 目录下 执行 "mkdir "建立目录 或是透过tftp下载文件
此时都看得到 目录和档案 但是执行"reboot"或是直接reset后 再重新mount后所有数据就全部消失了...
是我哪个步骤出了问题呢？请各位指导..thx

Jay,
能不能按照这个步骤，在BF527-ezkit 的Nand Flash 上创建 Jffs2 文件系统。
把你看到的详细信息贴上来？
1. cat /proc/mtd
2. flash_eraseall -j /dev/mtd0
3. mount /dev/mtdblock0 /mnt
4. cd /mnt
5. touch test

第五項 touch test
是指進入mnt / lost+found 存取嗎？？
像是使用mkdir ,rm 之類的指令？
還是說使用nanddump nandweite ？？？
nanddump nandweite 指令該如何使用呢??
可否舉例？？

從開機執行完上面的指令後 在nandflash執行掛載

2.Blackfin Linux Docs 所提供資訊中...有使用到 flasheraseall ,flashcp等指令 但我使用的版本沒有這些指令 flasheraseall 可 用 eraseall 取代 然而 flashcp 可以使用cp取代嗎？ 還是說需要使用flashw 指令 但我選擇他之後make無法成功....
3.可否給我們一份for 527的image檔 讓我們可以正常掛載nand flash並可以讓我們執行存取 好讓我們進行驗證？？？
